Question

How many litres of water can a cube of side 10 cm hold?

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is A 1

The amount of space that an object takes up is its volume.

Volume of a cube is given by
$V=\text{side}\times \text{side}\times \text{side}.$

A cube of side 10 cm has a volume of
$10\text{cm}\times 10\text{cm}\times 10\text{cm}=1000{\text{cm}}^3.$


We know that $1\text{litre}=1000\text{ml}$ and $1\text{cu cm}=1\text{ml}.$

$\therefore 1\text{litre}=1000\text{cu cm}$

Thus, a cube of side 10 cm can hold 1 litre of water.
